FIREARM.

Specification of Letters Patent.

Patented Oct. 13, 1914.

Application filed January 2, 1914. Serial No. 809,913.

To all whom it may concern:

Be it known that I, ALVAH E. GmMEs, a citizen of the United States,residing at Nor wich, in the county of New London and State ofConnecticut, have invented a certain new and useful Improvement in Firearms, of which the following is a specification.

My invention relates to tire arms and more particularly to single shotrifles of relatively small bore, my object being to provide an extremelysimple, cheap and effective form of ejector which will act,automatically, to throw out an empty cartridge shell, or will actforcibly, to start, and extract from the barrel, a stuck shell.

The invention is clearly illustrated in the accompanying drawings, inwhich Figures 1 and 2 are side elevations, partly in section, of theframe and a portion of the attached barrel, of an arm embodying my saidinvention; Fig. 1 illustrating the lock mechanism with the hammer downas if the arm had just been discharged, and Fig. 2 illustrating the sameparts as they appear just at the instant when a spent cartridge shell isbeing ejected from the barrel. Fig. 3 is a detached perspective View ofthe breech-block of the arm, and in Fig. 4: I have shown side and edgeviews of the ejector proper.

Referring to the annexed drawings, the numeral'lO indicates thebreech-frame of an arm and 11 denotes the barrel secured to the frame,as here shown, by screw-threads.

12 is the hammer, 13 the trigger, 14 the trigger spring, operating as ayielding spreader between the said trigger and the upper tang-portion ofthe frame, and 15 is a so-called kick main-spring abutting the notchedfront side of the hammer and secured, at its front end, to the underside of the barrel, by a post 16.

The breech, or recoil block 17 is pivoted in frame 10 at 17 in suchmanner that said block may have a downward drop when the hammer iscocked, or half-cocked as the case may be (see Fig. 2), and said blockis milled or otherwise, cut away, as at 17, to provide a recess in whichis located an ejector arm 18 which is pivoted in frame 10 at 18 and isformed with a rearwardly extending angle-arm 18 whose end lies in thepath of the breech-block 17, when the latter drops to its lowermostposition (see Fig. 2),

and so that the impact of the breech-block with said angle-arm willoperate to rock the free (upper) end of the ejector arm 18 rearward tothrow the cartridge shell out of the barrel; the said free end of theejector arm being suitably shaped, as at 18, to engage the head of theshell. The end portion of block 17 which is pivoted at 17 is formed witha downwardly extending, angular, portion 17 which is engaged by the freeend of a stiff spring 19 whose front end is secured to the barrel 11 bythe post 16 already mentioned. When the breech-block 17 is in its closedposition, as in Fig. 1 of the drawings, the spring 19 operates to holdthe said block closed. l/Vhen, however, the block is dropped slightlyand the angular arm 17 passes away from the vertical dot-and-dash lineso (Figs. 1 and 2) the 5 ring 19 then operates to throw the bloc: 17downward quickly and forcibly, thus causing said block to engage theejector angle-arm 18 with a hammer-like blow sufficiently strong to rockthe ejector arm 18 rearward and thus eject the empty shell from thebarrel with a quick movement. In the event that a shell should stick inthe barrel, the peculiar arrangement of the cooperating breech-block andejector arm is such that the downward movement of the said block,manually, will furnish sufficient leverage and power to start the stuckshell from the barrel. It will thus be seen that the described mechanismmay act as an automatic ejector, to throw the shell out of the barrelwith a rapid move ment or it may operate as an extractor to start astuck shell and withdraw with a relatively slow movement.

In order to start the breechblock on its downward movement when it isdesired to eject a shell, or for the purpose of loading the arm, I haveprovided, as here illustrated, a thumb-piece 20 which projects laterallyfrom one side of the said block, near the top portion of the latter.

My described improvement is of extremely simple, and inexpensive,construction yet it operates positively and is particularly convenientfor use with rifles of small bore.

Having thus described my invention, I claim as new and wish to secure byLetters Patent In a fire arm, the combination with a barrel and a breechframe, of a breech block pivoted in said frame and provided with arecess, an ejector arm pivoted in the frame and located in said recess,a spring having one end secured to the barrel, the breech block having adepending angular arm directly engageable with the free end of saidWitnesses: spring, and the ejector arm provided with a FRANK H. ALLErearwardly extended angle arm engageable ELSIE P. GRUNERT.

directly by the said recoil block as the latter drops.
